How can I tell if a ring is solid silver or just coated in silver?

You can buy a testing kit online; amazon has them. It requires you scratch or file through the surface somewhere that doesn't show and put a drop of special acid on it. It will change color depending on metal content. Very easy. Or you can ask a jeweler to do the same. If you buy a kit, read reviews carefully. Some of the vendors are selling acid that is past its expiration date and no longer works.

1. Check for Hallmarks or Stamps (with Singaporean Emphasis):

• "925" or "Sterling" are universal: These are still the most common and reliable indicators of sterling silver.
• Singapore Assay Office (SAO) Hallmark: In Singapore, the Singapore Assay Office (SAO) provides hallmarking services. A complete SAO hallmark consists of:
  • The SAO mark: A lion's head.
  • The standard mark: Indicating the purity (e.g., "925," "800").
  • The jeweler's mark: A unique mark identifying the manufacturer or retailer.
• Look for the Lion Head: If you see a lion head mark, it's a good sign the piece has been officially assayed in Singapore.
• Older Pieces: Older silver items sold in Singapore might have different hallmarks, especially if they were imported.

2. The Magnet Test (Still Applies):

• This test is universally applicable. Silver is not magnetic.

3. The Ice Test (Still Applies):

• This test is also universally applicable due to the physical properties of silver.

4. The Sound Test (Still Applies):

• This test is also based on the physical properties of silver and is applicable in Singapore.

5. The Tarnish Test (Still Applies, with a Note on Singapore's Climate):

• Humid Climate: Singapore's humid climate can accelerate tarnishing. So, if a silver ring tarnishes quickly in Singapore, it's not necessarily a stronger indicator of it being real silver compared to a drier climate, but it's still a sign to consider.

6. The Bleach Test (Use with Extreme Caution, Especially in Singapore):

• Potential Damage: Given the value of some jewelry in Singapore, it's even more important to avoid this test unless you're absolutely sure and willing to risk potential damage.

7. The Acid Test (Definitely for Professionals in Singapore):

• Reputable Jewelers: If you're unsure about a valuable piece, take it to a reputable jeweler in Singapore. Many jewelers offer appraisal and testing services.
• Singapore Assay Office: For ultimate certainty, you could consider having the piece assayed by the SAO, although this is usually for more valuable items.

Key Takeaways for Singapore:

• Prioritize Hallmarks: Look for the "925" or "Sterling" mark and especially the SAO lion head hallmark for assurance.
• Consider the Climate: Be aware that the humid climate in Singapore can affect tarnishing.
• Seek Professional Help: If you have any doubts, don't hesitate to consult a reputable jeweler or the SAO for professional appraisal and testing.
